Push mower deck/blade pitch

[mac1911]

Do push mowers need or work better with a pitch from front to rear. ?
I know most ride on mowers like a touch of pitch

I would suggest the many types of blades might have a part to play in that question. Also, the maker may have set that pitch into the wheel marks already and a fine measurement could reveal it if true. I would generalize that the maker knew and the engineers designed the machine to operate in a certain way.

I had to modify my old ryder to get my cut height where I needed it.
Then the pitch needed adjustment . Which lead me thinking about the push mower (hrx 217) . I did try it a notch higher in the rear but did not see much if any difference.
